The Schedule `referred to in these VLetters Patent and making part ofthe same. I

Figure 2, a sectional view on 'a larger scale, taken as indicated bythe line a: x'iu iig. 1, ot' the portion of `the apparatus embracing iny improvement. i

`Similar letters of reference indicate corresponding parts. My'improvementrelates to atomizers or spray-apl paratus, used for surgical and other operations or pur# poses, in which the draughtor current to produce the spray, or divide into atomsthe medicated or otherv lfluid, and to expel or direct it against the part to be treated, is established or produced by the agency ot` steam or vapor, formed in a generator carried by said apparatus, and` heatedfby a lamp connected with the latter. l i

In using such 4apparatus `for various surgical operapitions, it i'requentlyis necessary to stop quickly andl temporarily, for a longer orshorter period, -the action `of the spray onthe part being treated. This, heretofore, could only be done in one of two ways, namely,

' either by removing the'entireapparatus, which is objectionable, as Ywhen once set, its position, relatively to the wound orpart under treatment, should be pre? served, or by withdrawing theglampfrom under the generator, which does not immediately arrest the iiow ot" steam or vapor, andfis, on nianyiacc'ouuts, objec- `from thegenerator toior through the pipe. which es- 1 tablishes the current, as in inerely shutting oifescape from the generator, there would be great danger of x l `the latter bursting, by reason of Aits remaining closed for a prolonged period, with the lamp 'burning under i it, which might occur either purposely or accidentally, and during which time additional pressure isbeing formed inthe generator, with no provision for :its relief or escape.

\ To obviate these vention, which consists in a combination, with the draught-,Lor j'etpipe 'of the apparatus, or outletthereto, from the generator, of a two-way cock, of certain construction, and side outlet or escape-pipe,f'the whole being so arranged as that," without disturbing the apparatus, or removing ,the\1amp, `the spray may be intionable, but preferable, as regards safetygto a Imere stopfcock, operating only to Iopen and close 'the outletv amenities is the object, of my im shorter time, without risking explosion of the genera tor, by turning the cock so as to divert the flow from it through the side pipe, and .away from the `patient and operator; also, whereby, on'turning the cock to establish communication betweenthe'boilcr and blast or jet-pipe, the spray-action -may be as rapidly reas that, by still further turning it, ,all out-let from the generator may be temporarily stopped "to provide for erator.

ratus there represented is, in its general aspect and construction, similar to othersin ordinary use, A being the frame, B, the boiler, heated by a lamp, C, `and serving to supply steam, through au outlet or brauch, D, tothe jet-pipe or tube E, which establishes the current or G, and to be split or divided into spray, and' blown along the conducting-tube H, to the part or surface to be treated, said conducting-tube being suitably held to admit of its adjustment to such partor surface, and having a bottle or reservoir, I, under its inner'end, to catch the dlippi'ngs caused within it.

The generaljadiustment ofathe apparatus maybe or escape-pipe, M, branching from it in a direction' from itfto be projected either against the patient or operator.

drawing,4 through communication is established between the boiler B and jet-tube E, which keeps the vapparatus at Awork distributing the spray, but when said cock is turned to'put its main passage, a, lout of such through communication, and, through aid of the accident can possibly occur to -the boiler. i
